Understanding Heredity Reading

One _____________________ passes information on to the next.

• Offspring

• Generation

• Person

• Organism

This __________________ makes the new generation resemble the other members of their species, especially their parents.

What is it called when people breed animals or plants based on valuable traits?

• Choice breeding

• Selective breeding

• Interpretive breeding

• Organic breeding

Because Mendel's family didn't have the money for him to go to school, he joined a ___________________ where he studied the inheritance pattern of pea plants.

What did Mendel conclude from his studies?

• Plants have nucleii that multiply when bred

• Plants have a "factor" that transfers traits to their offspring

• Plants have a cell wall, so they transfer traits through the cell wall to their offspring

• Plants do not pass on traits to their offspring

How many years did Mendel experiment with pea plants?

What did scientists name the structures that looked like X's and hot dogs inside the nucleus?

• Alleles

• DNA

• Chromosomes

• Phelangi

An allele is a _________________ of a gene

What remarkable discovery proved Mendel's work?

• Each sex cell had just one set of chromosomes, not two

• Each sex cell had two sets of chromosomes, not one

• Each sex cell duplicated for a total of 4 chromosomes

• Each sex cell only contributed half of a gene

The information for an organism's traits is on the ____________________ it receives from both its parents.

• Nucleus

• Chromosomes

• Fibula

• Chodachrome
